How long could the lithium battery used?

What is the real lifetime of a lithium battery? Some people say three years, some mentioned five years and some say 500 cycles. If I use 300 cycles in 5 years. Can it use for seven or eight years?

The quality of lithium batteries is uneven, just like the high school entrance examination results. A good ternary lithium battery pack is 8 years for normal households or 300,000 kilometers for commercial use. The endurance performance is not more than 20%, quality lifetime warranty, different price. Lithium batteries generally have a total charge and discharge frequency of 500 to 3000 times, discharge rate of 0.5C to 15C, resistance of 1m? to 50m?, *voltage of 4.2V, *3V, nominal ternary lithium battery of 3.7V, according to electric motor rated Power, voltage series and parallel plus BMS management module protection board, anti-overcharge and over-current limit temperature control and other safety and life extension. That is, full battery cell 4.2V put to 0V and then recharge to 4.2V for one cycle, for lithium battery life and Safety, in actual use, the battery is discharged to 3V, which is protected by the BMS module management system. The actual power consumption is less than one-third. Each full charge-discharge cycle converted into three or five times per daily charge. The daily charge and discharge times of the lithium battery are about 10,000 times, that is, the normal use and good maintenance can used for about ten years. The normal use of lithium battery in my place has not been degraded for 6 years, waterproof and high temperature, special charger for lithium battery, voltage capacity and motor. Match, when not in use Avoid full storage.

In theory, the life of lithium titanate is stronger than that of lithium-iron phosphate battery. Because of the titanium non-metal material used in the negative electrode material of lithium titanate, the volume change of this material is small during multiple charge and discharge cycles, and the charge and discharge chemical reaction is almost there are no appendages in it, and there is no danger of penetrating the diaphragm.

How long does the lithium battery last?

Lithium titanate battery advantages of charge and discharge allow 3-5c impulse 8c stable discharge, low temperature resistance, low internal resistance, good cycle performance can be said to be 25,000 times, lithium iron phosphate battery cycle is 2000 times, the disadvantage is energy density It is lower than ternary or lithium iron phosphate. The weak deviation of low internal resistance and internal resistance leads to the difficulty of balancing the protective plates of lithium titanate battery. The life cycle of electronic products cannot keep up with lithium titanate life cycle. Lithium acid battery technology is an emerging issue, technology is not very mature, and there are potential risks of instability.

lithium iron phosphate battery has the advantages of charging and discharging 1-3c charging 4-5c discharge, charging above 0 degrees Celsius, discharging -15 degrees Celsius to 80 degrees Celsius, internal resistance lower than ternary, higher than lithium titanate, cycle performance 2000 times, 500-800 times greater than three yuan.

The price of lithium battery with the same capacity is very different. The lithium battery is very deep. Take 6040 lithium battery as an example. The price can be from 2800 yuan to 5,000 yuan. The difference is so much.

Lithium battery cycle charging 500 times, here five hundred times is not to say that each charge, but from low battery to 100%, such as from 20% to 100%, in fact, only 80%, 500 times after lithium ion activity It will decrease.

If 6020 lead acid replaced by 6020 lithium battery, there is no big difference unless you change the capacity of lithium battery to improve the battery life. Although lead-acid batteries are heavy, its technology is very mature and stable. If you change to lithium battery and could not accurate it right, it may out of power in the middle of your way and leave you no choice but walk with the vehicle.
